Calling Oldsman

Any ideas what this will do for me? Is it worth to even try myself? how much work will I have to do to get these to fit? Thanks in advance!

the good old 2.3 head.

is it worth for you to try yourself???????? well that depends.

the heads bolts up but you have to open up 4 water jackets. use the 2.4 cam towers. everything bolts up fine. Now if you use the stock head gasket, being the 086 head has a way smaller combustion chamber you will be running 11.4:1 compression. so high octane fuel to even 100and up octane. you also will need the HO intake manifold and HO exhaust manifold. so you will need new down pipe.

Now to really benefit from the head upgrading the cams will really help. stock cams don't really utilize the flow of the head. so if you go with HO cams or close to the same specs you will need to do a clay test on the motor. why? more than likely your valves will be hitting the pistons. which is no good. With the secret cam swap you should be ok but clay testing it is still not a bad idea.

now away around having the high compression and valve clearence is to use a .093 copper headgasket this would give ya around 10.5:1 compression which is more streetable. but the cooper gasket would require o-ringing either the block or head and after install and run for little bit then you would need to retorque it down and periodically would heave to check the torque of the head.

So unless you plan on doing like i have and pull the top half all apart and have it down for awhile and build it back right and careful then i would say it is not worth it for you.
